I have cohorts tracked in format YYYYMMDD (ex. 20220101). I try to separate cohorts by a date (20230110) so user who shoot the event before would be separated from the ones that shoot it after.
I try doing it by writing in “performed by Any User” window two groups of users:
- I group: cohort => 20230110
- II group:cohort < 20230110
And then in the “Segmentation by” window:
- event
- where Historical count = 1st
However I find users from II group in I group - when I do View User Stream and look at user profiles I see in II group users with cohort later than the 20230110. What is the problem and how can I deal with it?
